Characteristics of Electron Transport in Molecular Single-Atom Transistors Based on Atoms of Sc, Cr, Ru, Rh, and Pt

Abstract

The transport characteristics of single-atom transistors with charge centers based on Sc, Cr, Ru, Rh, and Pt atoms are studied. Single-particle electron spectra of molecules of the coordination compound of these atoms with an aurophilic terpyridine derivative in different charge states are calculated and their features are analyzed. The effect the length of linkers have on the properties of effective tunnel barriers and transport characteristics of a single-atom transistor is studied.
